Although the Chiefs have a featured back in Jamaal Charles, I wouldn't be surprised if they drafted a back in the middle rounds as a backup to replace Peyton Hillis, who underwhelmed last year. Capable of being a featured back somewhere, Bell would be a good value here.

The Raiders defense allowed a 66.0 percent completion rate, fourth-worst in the league, 28 passing touchdowns, only seven teams allowed more, and intercepted 11 passes. The Raiders have added free-agent cornerbacks Mike Jenkins and Tracy Porter, but both signed just one-year contracts with the club.

McDonald (6-3, 205) led USC in tackles (110) this year and he was third on the team in 2011 with 67. In addition, McDonald had 6.5 tackles for loss, two interceptions and one sack this year. The hard-hitting free safety is the son of ex-NFL safety Tim McDonald.

Whether or not the Vikings have their franchise quarterback in Christian Ponder (or Joe Webb) remains to be seen, but it seems unlikely. Webb was horrible in the playoffs with Ponder out, but Ponder was not much better in his second season as Adrian Peterson rushed for more yards than Ponder had throwing in the team's final 10 games.

Jones has thrown for 4,000-plus yards in each of the past three seasons and has a total of 16,646 yards and 123 touchdowns in his four seasons in Norman.

The team added Matt Cassel as a free agent to be a backup to Ponder, but it would be wise to add a young quarterback to groom as well.

2013 NFL Mock Draft - By Team
Aside from viewing this mock draft by round,
you can view it by NFL franchise.

Porter had an off year in the Aggies' new 4-3 defense compared to the previous season in a 3-4 scheme. Although he finished second on the team in sacks behind Damontre Moore, Porter had only 3.5 sacks this season. In 2011, he had 9.5 sacks and 17.0 tackles for loss.

In addition, Daryl Washington will be suspended for the first four games of the season due to a violation of the league's performance-enhancing drugs policy.

Bills tight end Scott Chandler will become a free agent after this upcoming season.

The younger brother of Eagles guard Jason Kelce, he led his team in receiving this season: 45 receptions for 722 yards and eight touchdowns. He scored four of those touchdowns in his final three games and had a career-high 123 yards against Duke in the Belk Bowl to close out his collegiate career.

After trading Revis to the Bucs, the Jets will likely use a pick (or two) to add a cornerback(s) in the draft. Gratz has good size (6-0, 198) and he led UConn with three interceptions and 11 pass breakups.

After signing guard Andy Levitre in free agency and using their first-round pick on Cooper in this mock, the Titans continue to bolster their interior offensive line with Schwenke here. It has gone from being a liability, arguably the team's biggest, to a strength now.

With the Panthers projected to start Haruki Nakamura and Charles Godfrey at safeties, the team is likely to target a safety at some point in the draft. In fact, it wouldn't be a huge surprise if they select Kenny Vaccaro in Round 1. That said, they get a nice value here in the fourth round with Rambo.

While the Chargers have a featured back in Ryan Mathews when healthy, his (lack of) durability is the problem. He has missed a combined 10 games of the past three seasons.

With Davis, there are some concerns with his durability as well and ball security, but he has all of the physical tools. Despite weighing 227 pounds, Davis ran a 4.37 forty at the combine and benched 31 reps at the combine.

Back in 2010, Davis ran for 1,322 yards and 13 touchdowns and was a first-team All-SEC selection along with Marcus Lattimore. (Alabama's Mark Ingram and LSU's Stevan Ridley were second-team selections that year.)

Provided he stays healthy and improves his ball security, he could become a steal.

Not only did the Dolphins trade Vontae Davis to the Colts last offseason, the team lost Sean Smith to the Chiefs in free agency this offseason as well. The Dolphins signed Brent Grimes to a one-year contract, but they will likely use an early-round pick on the position.

In addition to signing left tackle Jake Long, the Rams should use a pick or two on bolstering their offensive line through the draft. They added D.J. Fluker earlier and now add his teammate here.

While Jones is only one man, he has played multiple positions for Alabama and can help the Rams anywhere necessary. A highly intelligent and versatile player, Jones has won the Outland Trophy at left tackle, had started at guard and won the Rimington award at center last year.

With Felix Jones now a free agent and DeMarco Murray a perennial injury risk, the Cowboys should look to add a running back in the middle rounds. Ellington is not a big back (5-9, 190), but he was productive at Clemson with back-to-back 1,000-yard seasons.

Bostic has finished in the top three in tackles for the Gators in each of the past three seasons and led the team in 2011. A big hitter, Bostic helped himself at the combine as he finished third in the forty and fourth in the 20-yard shuttle among linebackers.

While he may lack mobility and maturity, Bray has as much arm talent as any other quarterback in this year's draft class. Bears quarterback Jay Cutler is entering the final year of his contract so Bray gives them some insurance.

While it's certainly possible that Andre Smith ends up re-signing with the Bengals, he is currently a free agent and Williams gives them a viable option at the position.

Son of 11-year NFL veteran defensive end Brent Williams, who spent the majority of his career with the Patriots, Brennan (6-7, 315 pounds) missed the team's final four games after tearing his labrum, but he is a good value in the fourth round.

The team's starting strong safety Brandon Meriweather was lost for the season in Week 1 and he has missed a total of 20 games in the past two years combined. The Redskins will need to add reinforcements throughout their back four via the draft and free agency and add the converted wide receiver from Georgia Southern here.

Having to face Aaron Rodgers, Jay Cutler and Matthew Stafford at least six times per season, the Vikings can never have too many cornerbacks. Plus, Antoine Winfield was released earlier this offseason.

As noted earlier, no other quarterback has been sacked as much as Rodgers over the past three years, which makes adding more reinforcements a smart move.

Although he started his college career at tight end and he's perhaps a better fit at guard, Quessenberry was an All-WAC selection as a left tackle. In fact, it's his versatility that could make him a Packer.

"... A team like Green Bay, they see me at all five, and thatís where my value is, being able to play all those positions and handle all that. Iíve gotten real positive feedback from them," Quessenberry said, per Rob Demovsky of the Green Bay Press Gazzette.

Seahawks right tackle Breno Giacomini (12) was one of the most penalized players in the league as Doug Free (15) was the only lineman to have more. A three-year starter at right tackle (one year) and left tackle (two years), Bakhtiari gives the Seahawks depth but he may have to move inside at the next level.

After the infamous fax incident, the Broncos lost Elvis Dumervil to the Ravens this offseason. In addition, the Broncos cut D.J. Williams this offseason. By drafting Gooden, the Broncos get a very athletic linebacker in return.

As a workhorse back, Taylor carried the ball 322 times for 1,530 yards last season, but he has rushed for 1,100-plus yards and double-digit touchdowns in each of the past three seasons. Coach Jim Harbaugh was still at Stanford for the first of those 1,000-yard seasons.

The Ravens did not re-sign Ed Reed and released Bernard Pollard while adding Michael Huff via free agency this offseason. While Evans did not receive as much attention as Matt Elam, he had 83 tackles, 4.5 tackles for loss, three interceptions and six passes defended last year.

Another Gators tight end from my home state (CT) leaving school after his junior season, Reed was a first team All-SEC selection and led the team in receiving with 45 receptions for 559 yards and three touchdowns.

Reed needs to improve his blocking (then again, how many tight ends don't these days?), but he has the ability to create mismatches in the receiving game.
